Developed and delivered a new Promotional Advertisement Section for the Tetiana-Nuraddinova/green-harvest repository, focusing on enhancing the website’s promotional capabilities. The work centered on implementing a responsive front-end feature using HTML and CSS, ensuring consistent presentation across desktop, tablet, and mobile devices. The updated HTML structure included a heading and paragraph to clearly communicate discount offers and health messaging. Emphasis was placed on accessible markup and maintainable code, with multiple commits dedicated to refining the feature and validating changes through initial test coverage. No major bugs were addressed, as the primary focus remained on feature delivery and code quality.
